Since several days ago, we've found we can't send email to any other mail server, like to firstname.lastname@example.org, email@example.com etc, but we can receive emails from these. Before, our mail server works quite well, the problem only occurs these days.
Now when I send email to address like firstname.lastname@example.org, I will receive a notification from protector," Delivery Status Notification (Failure)", it mentioned "<00>] XMail bounce: Rcpt=[some address];Error=[417 Temporary delivery error]".After several retries, it eventually failed to send out the email,"<00>] XMail bounce: Rcpt=[SOME ADDRESS];Error=[The maximum number of delivery attempts has been reached]".
From the protector suse linux interface, I can send email in the following way:
telnet freemx1.sinamail.sina.com.cn 25
mail from:email@example.com rcpt to:firstname.lastname@example.org
Hense I don't think the problem was caused by the network issue.
Is it the problem of the mail server or lotus protector? How can I diagnose it and figure out a solution? Thx a lot.
